The car ran for about 500 miles before it started smoking again. It isn't the turbo, as the shaft on the new part has no unexpected movement. It's also been looked at by the garage, they said it's fine.
It seems to be coming from the rocker cover, which recirculates dirty sump gas back in to the clean air duct, going in to the turbo.The pipe is dripping with oil, when you remove it from the clean air duct. It also makes sense as the blue smoke only comes off when you foot off (engine keeps pulling air through, but without diesel combustion, it comes out as blue smoke). When I put my foot lightly back on the accel, blue smoke completely disappears. Also, no blue smoke under acceleration.
Disappointingly though, I replaced the rocker cover but the oil still comes through. the recirc pipe still sodden with sump oil. It's burning about 0.5 litre per 500 miles.
Any ideas what might be causing that and how to fix?
